Address:	Gautam Buddh Nagar, Uttar Pradesh, 201301
Website:	MI Mobile

My name is suresh chandra pandey, i purchase redmi note 3 (Gold 16gb) phone from flipkart dated: 26aug-2016. Invoice no.#blr_wfld[protected]

I have faced one issue in apr-may'2017 related to vibration not working when there is an incoming call. So i have taken my mobile and get repaired from mi service centre situated in sec-18, noida. I was happy with the mi work.

But now, on 26july-2017 onward my phone started creating issue in charging. So i took my phone to nearest service "satguru communication", sec-27, noida on 31st july-2017. That time i was not carrying my bill with me as i have shifted my home so some document misplaced. So the service centre checked my phone and said it is out of warranty and you will be charged with service charge and repairing amount additionally. He said they will inform me via phone call about the estimate repairing amount.in the evening i received a call from them and they told me it will be charged 650 rs/- as charging jack need to be replaced. I was not okay with the amount so next day i took my phone back from them. At this time they charged me 118rs/- as an service charge for only checking the mobile.

Yesterday i found my flipkart invoice and found my mobile is still under warranty as per date mentioned in invoice. So i again take my mobile to the same service centre today dated: 8aug-2017 and again they are replying that it is out of warranty and i will be charged 118rs apart from repairing charge. They will inform me via a call for the new estimation charge now.

Now my query to mi is why service centre is charging me if it is under warranty.in service order they have mentioned in cosmetic: no warranty seal or warranty seal damaged. I dont care for this as i have no idea of this seal.
I have taken my mobile to mi service centre not any local shop so there is no meaning of getting warranty seal damage. Request you to process my work free of cost as it is under warranty as per the date of purchase. Looking for your revert on this.
